OsmoMGW, the Osmocom Media Gateway, is a Media Gateway for handling user plane (voice) traffic in cellular networks.

OsmoMGW supports the IETF MGCP (Media Gateway Control Protocol) for control from Call Agents, such as those present in OsmoBSC and OsmoMSC.

At the moment (October 2017), OsmoMGW only implements RTP proxy / RTP bridge type endpoints, to each of which two RTP connections can be established.

OsmoMGW is the generalized version of an earlier much more special-purpose implementation called osmo-bsc_mgcp.
